SPECIFICATION forming part of Letters Patent No. 479,220, dated July 19, 1892.

Application filed March 9, 1892. 1 Serial No. 424,337- (No model.)

tributing chamber, from which radiate aseries E represents an oil-supply pipe extending of tubes to the outer burner-chamber, and in this instance through the combustion tubes through which tubes the vapor is conveyed and chamber into the inner or distributing and distributed to the vapor and combustion chamber. By thus exposing said pipe to the 25 chamber in effect as it is by the construction heat of the burner the vaporization of the oil shown in Figs. 1 and 3. In this instance the is greatly facilitated. It will, however, be un air is supplied between the inner and outer derstood that the chamber a is essentially a chambers.

In this instance, instead of the rawithin the inner combustion-tube and prodiating tubes, we employ radiating deeplytects said chamber from drafts within the flanged open channels, which serve'the same burner. o purpose as the tubes and slots shown in the In Fig. 2 we showa modified form of burner,

other figures. Fig. 5 is a modification of the in which, instead of the annular troughvapor-distributing chamber or drum shown in shaped distributing-chamber shown in Fig. 1, Fig. 2, and in which the sides of the chamber we employ a cup or drum shaped chamber a, are made sufficiently high to protect the va located centrally in the burner and having 5 5 por against air currents and drafts, and theretubes d radiating from about its sides and by rendering a cover over said chamber undischarging at a slight inclination into the necessary. vapor and combustion chamber 1). These In Figs. 1 and 2, A and 13 represent the intubes d serve exactly the same purpose as ner and outer combustion-tubes and O reprethe slots d, and the said chamber has a close I00 50 sents the burner bowl or base in the several cover, as has the chamber in Fig. 1.

figures. In Fig. 4: the construction resembles that shown in Fig. 2, excepting that in this instance deeply-flanged open channels (1 are employed instead of closed tubes. In any case the vapor in its travel from the inner to the outer chamber requires no more protec tion than will shield it from air drafts or currents, because it being considerably heavier than air will travel and distribute by gravity. Hence an open channel can be used, as well as a covered one, if the side-wall protection be deep enough to protect the vapor from the drafts and currents, as described. Otherwise there is no difierence between this form of burner and the form shown in Fig. 2.

Fig. 5 shows the principle of open'channel or duct, disclosed in Fig. 4 particularly, applied to the distributingchamber. In this form we employ a chamber or drum with very deep sides, and by reason of the depth of sides we get practically the same efiect as by means of a cover over the chamber, it being understood that the cover over said chamber serves substantially the same purpose as the cover over the channels or ducts or passages seen in the other figures-via, to protect said channels or passages from air drafts or movements that might carry away the vapor or disturb its flow or distribution.

The bottom 12 forms the bottom of the vapor and combustion chamber, and the vapor distributes by gravity between the ends of the vapor-channels, where they discharge onto said bottom I), so that a uniform flame is maintained all around the burner the same as if the channels were numerous enough to supply every portion of said bottom I) with an equal supply of vapor without lateral distribution at said points. This bottom I) is closed, so as to prevent the escape of vapor down through it and to prevent the admission of air, and since there necessarily is only partial combustion of the vapor immediately upon or over said bottom I), owing to lack of sufficient air to make combustion complete, the vapor that is unconsumed will distribute itself laterally over said bottom and maintain a supply to combustion above between the tubes A and B. Hence, also, the perforations for the admission of air may come down to the immediate bottom I), and the burnerwill operate as hereinbefore described.

Having thus described our inventiomwhat We claim as new, and desire to secure by Letters Patent, is-

1. A vapor-burner provided with a vapor and combustion chamber and. a vapor-distributing chamber and channels to convey the vapor from the distributing-chamber to the vapor and combustion chamber, substantially as described.

2. A vapor-burner havinga vapor and 001m bustion chamber closed at its bottom against admission of air and having air-inlets in its sides, a vapor-distributing chamber, and channels or ducts leading from said distributing- .chamber to the said vapor and combustion chamber, substantially as described.

Witness our hands to the foregoing specification this 5th day of March, 1892.
